ABSTRACT: Most studies concerning the origins of parliament in the Spanish kingdoms have focused on the social changes in the composition of these royal assemblies, especially from the thirteenth century. This paper will instead analyse consultation, assent and deliberation at large gatherings of kings and nobles in the twelfth century to suggest this phenomenon as a key process to understand the development of the cortes from the curias plenas.

OBJETIVO: Aplicar cinco modelos de inventarios, para obtener la cantidad de pedido y el punto de reorden, en el caso de un producto con demanda y tiempo de entrega discretos, aleatorios, independientes y conocidos, considerando descuentos en el precio de compra por adquirir mayores volúmenes y el costo de pedido semivariable. MATERIAL Y MÉTODO: Los modelos utilizados han sido el de la cantidad económica de pedido (CEP), aplicado para una demanda y tiempo de entrega aleatorios, el de un nivel de servicio meta (NS), el de distribución normal de la demanda (DN), el algoritmo de Eppen y Martin (EM) y el modelo de Lee y Rim (LR). RESULTADOS: Las diferencias en los resultados se han dado en el valor del punto de reorden con los modelos NS y LR, que han dado un valor más alto, lo que lleva a un mayor costo del inventario. CONCLUSIONES: Todos los modelos coinciden en la cantidad de pedido, lo cual se debe al descuento en el precio unitario que se logra al colocar un pedido mayor; tres de los cinco modelos coinciden en el punto de reorden y al parecer es la decisión correcta en este caso práctico.

OBJECTIVE: To determine the economic impact generated by a traditional isthmian “Vela” in El Espinal, Oaxaca, Mexico. MATERIAL AND METHODS: A cost-benefit analysis was carried out, through the review of financial documents and a survey applied to 120 members, referring to the expense used in the organization and assistance of a traditional Vela. RESULTS: The investigation allowed us to know the economic impact generated by a Vela, an amount that gets to $2,056,456.80, of which 91.37% comes from the indirect effect, while only 8.63% is derived from the direct effect. Consequently, the indirect effect is relatively greater than the direct one. CONCLUSIONS: The economic impact generated by a traditional Vela has a significant effect on the municipality of El Espinal. Most goods and services required to organize and carry out this festivity are provided by formal or informal local commerce and brought about by people from the region. These festivities have also had a great influence on the creation and preservation of trades related to ornament, clothing, food, music, among others.

OBJECTIVE: To develop a social marketing proposal with effectively designed social action efforts aimed at influencing behavioral changes and impacting the inhabitants of the Puuc Biocultural region in Yucatan, Mexico.   MATERIAL AND METHOD: The research is descriptive, non-experimental and quantitative and involved the administration of two instruments applied to inhabitants of the region; the first one to learn about eating habits and the second one about the most used means of communication.   RESULTS: Among the main findings, evidence was found on the consumption of processed and ultra-processed foods that brings as an effect the loss of food culture. Also, access to the internet and the use of social networks have managed to penetrate in a vertiginous way, being WhatsApp and Facebook those with a higher frequency of use among the inhabitants of these contexts.   CONCLUSIONS: This work provided insight into the habits of the target audience and facilitated the design of messages and strategies for digital media, as distribution channels adapted to the context. The results are discussed in the light of scientific studies focused on food culture in Mexico; and the availability and use of information and communication technologies.
